摘要： A method and apparatus for providing foam resin insulation for a vessel, such as a water heater. The water heater includes a tank to contain water to be heated and has a plurality of openings to receive components of the water heater. A jacket is spaced outwardly of the tank to provide a space therebetween to receive foam resin insulation. Prior to introducing the resin into the space, an elongated member, such as a rod, is engaged with the opening in the tank and the rod extends outwardly through an aligned opening in the jacket. A resilient pad, which is movable on the rod, is compressed against the outer surface of the jacket to seal the space between the jacket opening and the rod. A liquid foamable resin is introduced in the space between the tank and the jacket and expands to fill the space and provide an insulating layer.

摘要： A clamping apparatus for use in applying foam resin insulation between the tank and the outer jacket of a water heater. The jacket of the water heater is spaced outwardly of the tank to provide a space that receives a foamable resin, such as polyurethane. The upper end of the jacket is enclosed by a thin, sheet metal cover. To clamp the cover to the jacket and prevent deformation of the cover due to the pressure of the resin foam, a clamping mechanism is utilized which includes a plate or clamping member that is positioned flatwise against the cover, and a clamp assembly secures the clamping plate to the upper end of a flue, or other tubular opening in the tank. In a preferred form, the clamping mechanism consists of a resilient, expandable plug which is inserted within the opening in the tank and is expanded outwardly into tight engagement with the wall bordering the opening to secure the clamping plate to the tank.
摘要翻译： 一种用于在水箱和热水器的外套之间施加泡沫树脂绝缘的夹紧装置。 热水器的护套与罐隔开，以提供容纳可发泡树脂（例如聚氨酯）的空间。 护套的上端由薄的金属板盖住。 为了将盖子夹紧到护套上并防止由于树脂泡沫体的压力引起的盖子的变形，使用夹紧机构，该夹紧机构包括平板地靠在盖子上的板或夹紧构件，并且夹具组件固定夹紧板 到烟道的上端，或者罐中的其他管状开口。 在优选形式中，夹紧机构由弹性的可膨胀塞子组成，该塞子插入箱体内的开口内，并向外膨胀，与与开口相邻的壁紧密接合，以将夹板固定到罐体上。

摘要： A method of coating the surface of semi-rigid porous materials such as open cell foam or fibrous compositions with a thermoplastic adhesive in powder form which will reactivate. The powdered adhesive in a size range of 0-600 microns will remain on the surface of such materials even when cell diameter of the foam or space between fibers is larger than adhesive particle size. High porosity is maintained in the coated product. First a thermoplastic adhesive in powder form is dispensed uniformly onto the surface of a carrier belt which is coated with a release agent and is moving continuously. The adhesive advances to a preheating station where the adhesive is plasticized and will adhere to the carrier belt to prevent movement, after which the foam or fibrous material is placed on the adhesive which is adhered to the belt. The adhesive and material advance to a second heating station where the adhesive is fully melted to allow the adhesive to bridge cells in the foam or space between fibers. The material and adhesive then advance to and through a cooling station where temperature of the adhesive and material are reduced to allow the adhesive to resolidify and the composite to release from the carrier belt and exit the machine.
摘要翻译： 将半刚性多孔材料如开孔泡沫或纤维组合物的表面用粉末形式的热塑性粘合剂涂覆的方法将会重新激活。 尺寸范围为0-600微米的粉末状粘合剂即使在泡沫的泡孔直径或纤维之间的空间大于粘合剂颗粒尺寸时，也将保留在这些材料的表面上。 涂层产品保持高孔隙率。 首先将粉末形式的热塑性粘合剂均匀地分配到涂覆有脱模剂并继续移动的载体带的表面上。 粘合剂前进到预热站，其中粘合剂被塑化并且将粘附到载体带以防止移动，之后将泡沫或纤维材料放置在粘附到带上的粘合剂上。 粘合剂和材料前进到第二加热站，其中粘合剂完全熔化，以允许粘合剂将泡沫中的细胞或纤维之间的空间桥接。 材料和粘合剂然后前进并通过冷却站，其中粘合剂和材料的温度被降低以允许粘合剂重新固化，并且复合材料从载体带释放并离开机器。

摘要： The subject matter of this invention relates to a method of making glass fiber mat reinforcement material with a thermoplastic adhesive powder. Fiberglass strands are chopped and randomly air dropped onto a Teflon.RTM. coated conveyor belt to form a loose mat. A water mist is then applied to the loose mat and transport belt, before a powdered adhesive is dispensed. Heat is applied to plasticize the adhesive and finally the adhesive is solidified by cooling. The adhesive will then release from the transport belt and is adhered to the material forming the fiberglass reinforcement mat.
